SPECIFICATION forming part Of Letters Patent NO. 294,623, dated .March4:, 1884. Application filed October 5,1883. (No model.)

To ctZZ whom it may concern-.-

Be it known that we, WI LIAM HOPPER and ISAIAH J. ALLEN, of Jefferson,Greene connnow in use, all as hereinafter fully described,

and specifically set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of our im proved machine. Fig. 2 is aplan viewof a part of the same. Fig. 3 is aperspective View of thedropping-slide. Fig. 4 is a section through one of the hoppers and thedroppingslide; and Fig. 5 is a perspective view of one of the dentersand part of the apparatus for working the same.

The seed-hoppers a rest on the frame-bars b and 0 above the hollowfurrow-opening run her-stock cl, through which the seed falls from thehoppers, out of which it is dropped by the slides e through holes f, theslides being arranged in the slideways g and operated by the arms h ofthe rock-shaft t. The droppingslides have an opening,'j,- through whichthe seed falls, and they are provided with an adjusting-plate, k, toregulate the width of the,

openings for graduating the quantity dropped. The adj ust-ing-plates aresecured by screws Z. The rock-shaft '5 is mounted on supports m, and isconnected by an arm, n, and rod 0 with a crank-pin, p, on a piniomq,that gears with a master-wheel, s, on the aXle t, which is keyed to thewheel a, to be turned by it. The wheel sis fitted loose on the axle t,and is held in gear with a clutch, o, thereon by the spring w. Saidwheel is also provided with a lever, w, to The arm a also has a rod, 3connected with it, that eX- tends back, and is connected with the crankzof a rock-shaft, a, which carries a dentingcranlgb, at each end, to beswung down at over the holes f and drop the seed.

the same time that the seed drops, to dent the ground at the placeswhere the seedlies, for guides to check the rows by. The slides e aremade to drop the seed at the moment the denters touch the ground byhaving slots '0, iii-which the slideshifting arms h work, so as only toshift the slides e by quick short movements just prior to the ends ofthe movements of the said arms h, which swing much farther than theslides 6 move, the slides resting during the larger portion of themovements of the arms. Besides the denters b, to mark the places wherethe seed" is dropped, we have pointers d, to drop on the dent made bythe denter in the last row planted as a test of checking the rowssquare, said pointers to be used singly, according to which side of themachine the implanted ground lies. These pointers are formed on the endsof the bent rods 6, which are hinged to the respective sides of themachine at f, and have stays 9 These pointers d are suspended hinged ath. g by cords z" from levers j, pivoted in the fulcrumstuds 7c, and theyhave springs L, that hold the pointers up, except when they are thrustdown by rock-shaft i, which has an arm, m, for each lever, and raises itto let the pointer drop at the same time that the dropper-slides areshifted v The pointers d are hinged to the machine in the range of thedroppers, and thus check the rows square to the rows checked by thedenters b. WVhen the pointer of one side of the machine is not to beused, it is shifted up and secured in the vertical position representedat the rear side of Fig. 1. The pinion q is designed to be onethird ofthe size of the wheel '8, for the purpose of making three drops to onerevolution of the truck-wheels, and the denters bl are located adistance back of the droppers equal to one-third of the travel of thetruckwheels at each revolution, to dent the ground in the place of thelast seed dropped and while the'seed is being dropped in the next .placeahead. \Vhen starting at the side of to be clutched by the spring. \Vealso employ driving-guides 0 to gage the driving of the machine by thelast rows planted, said driving-guides o consistin g of bent rods hingedto the sides of the machine at the rear, to be suspended over thelast-planted rows by a cord, 1), which we connect to both of said guidesand arrange through a pulley, (1, 0n the prop s, the cord being ofsuitable length to suspend one guide in the working position whileholding the other up, and so that said cord can be readily shifted tochange the guides by running forward and backward through the pulley.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- M 1.
